Is TSM 3.7.3.6 Stable?

[T.Y. Wu]

To support Fibre Channel 3590 interface, I need to go up to 3.7.3.6.  Is
this a stable level for production?  One entry dated 7/17 stated that
tape reclaim or del vol would crash the server at this level.   Has
anybody else bad experience with 3.7.3.6?

Our server environment:  M80/3494/3590, AIX 4330-ML04, TSM 3.7.2.0.
Atape and atldd are all current.

Thanks, T.Y.
